filmic blender issues
In your version of Blender [2.79], filmic is already integrated into Blender.

You can see in the active dropdown menu: View Transform > Filmic

It doesn't need to be manually installed anymore.

Nevertheless, you can still use the old configuration, but there is no need to do so.  


  For more details see the original Filmic Blender Configuration, which can still be used as an alternative to the builtin Blender configuration.
